* valops.c (search_struct_field): Change error message to treat
return value of 0 from value_static_field as meaning that field is
optimized out.
(value_struct_elt_for_reference): Ditto.
* values.c (value_static_field): Treat an unresolved location the
same as a nonexistent symbol. Fix PR gdb/635.
deprecated_grub_regcache_for_registers.
* values.c: Include "regcache.h".
(value_being_returned): Update. Use
deprecated_grub_regcache_for_registers to extract the register
buffer address.
* value.h (value_being_returned): Change ``retbuf'' parameter to a
``struct regcache''.
* Makefile.in (values.o): Add dependency on $(regcache_h).
* inferior.h (run_stack_dummy): Change type of second parameter to
a ``struct regcache''.
* valops.c (hand_function_call): Change type of retbuf to ``struct
regcache''. Allocate using regcache_xmalloc, clean using

regcache_cpu_no_passthrough instead of memcpy to copy the buffer.

2001-12-10 Fred Fish <fnf@redhat.com>
* values.c (value_fn_field): Add physname variable. Use a minimal
symbol if we don't find a full symbol. Remove setting of the new
value's type since that was already done by allocate_value().
Remove obsolete commented out error call since callees need to
handle a NULL return, which is possible result not an error.
* eval.c (evaluate_subexp_standard): Move check for inlined
functions to precede attempt to dereference a NULL argvec[0].
address of structure members.
* gnu-v3-abi.c (gnuv3_rtti_type): Cast to base type before
attempting to access vtable pointer. Set using_enc_p if we cast.
(gnuv3_virtual_fn_field): Call value_cast with structure rather than
structure pointer. Cast to base type before attempting to access
vtable pointer.
longer disagree on how big pointers are.
* findvar.c (value_from_register): Remove special case code for D10V.
* printcmd.c (print_frame_args): Same.
* valops.c (value_at, value_fetch_lazy): Same.
* values.c (unpack_long): Same.
* gdbarch.sh: Changes to effect the following:
* gdbarch.h (GDB_TARGET_IS_D10V, D10V_MAKE_DADDR,
gdbarch_d10v_make_daddr_ftype, gdbarch_d10v_make_daddr,
set_gdbarch_d10v_make_daddr, D10V_MAKE_IADDR,
gdbarch_d10v_make_iaddr_ftype, gdbarch_d10v_make_iaddr,
set_gdbarch_d10v_make_iaddr, D10V_DADDR_P,
gdbarch_d10v_daddr_p_ftype, gdbarch_d10v_daddr_p,
set_gdbarch_d10v_daddr_p, D10V_IADDR_P,
gdbarch_d10v_iaddr_p_ftype, gdbarch_d10v_iaddr_p,
set_gdbarch_d10v_iaddr_p, D10V_CONVERT_DADDR_TO_RAW,
gdbarch_d10v_convert_daddr_to_raw_ftype,
gdbarch_d10v_convert_daddr_to_raw,
set_gdbarch_d10v_convert_daddr_to_raw, D10V_CONVERT_IADDR_TO_RAW,
gdbarch_d10v_convert_iaddr_to_raw_ftype,
gdbarch_d10v_convert_iaddr_to_raw,
set_gdbarch_d10v_convert_iaddr_to_raw): Delete declarations.
* gdbarch.c: Delete the corresponding definitions.
(struct gdbarch): Delete members d10v_make_daddr,
d10v_make_iaddr, d10v_daddr_p, d10v_iaddr_p,
d10v_convert_daddr_to_raw, and d10v_convert_iaddr_to_raw.
(startup_gdbarch): Remove initializers for the above.
(verify_gdbarch, gdbarch_dump): Don't verify or dump them any
more.
* d10v-tdep.c (d10v_register_virtual_type): Rather that
claiming the stack pointer and PC are 32 bits long (which they
aren't), say that the stack pointer is an int16_t, and the
program counter is a function pointer. This allows the rest
of GDB to make the appropriate conversions between the code
pointer format and real addresses.
(d10v_register_convertible, d10v_register_convert_to_virtual,
d10v_register_convert_to_raw): Delete function; no registers
are convertible now, so we use
generic_register_convertible_not instead.
(d10v_address_to_pointer, d10v_pointer_to_address): New gdbarch
methods.
(d10v_push_arguments, d10v_extract_return_value): Remove special
cases for code and data pointers.
(d10v_gdbarch_init): Set gdbarch_ptr_bit to 16, so that GDB and
the target agree on how large pointers are. Say that addresses
are 32 bits long. Register the address_to_pointer and
pointer_to_address conversion functions. Since no registers are
convertible now, register generic_register_convertible_not as the
gdbarch_register_convertible method instead of
d10v_register_convertible. Remove registrations for
d10v_register_convert_to_virtual,
d10v_register_convert_to_raw, gdbarch_d10v_make_daddr,
gdbarch_d10v_make_iaddr, gdbarch_d10v_daddr_p,
gdbarch_d10v_iaddr_p, gdbarch_d10v_convert_daddr_to_raw, and
gdbarch_d10v_convert_iaddr_to_raw.
(EXTRACT_STRUCT_VALUE_ADDRESS): Change to a function with
predicate.
* gdbarch.h, gdbarch.c: Regenerate.
* values.c (value_being_returned): Change the reference to
EXTRACT_STRUCT_VALUE_ADDRESS_P to a function call.
Changes by Jim Ingham:
* values.c (value_change_enclosing_type): New function. If the
new enclosing type is larger than the old one, we need to allocate
more space.
* value.h: Add value_change_enclosing_type prototype.
* valops.c (value_cast): Use it.
(value_assign): Use it.
(value_addr): Use it.
(value_ind): Use it.
(value_full_object): Use it.
2001-05-07 Daniel Berlin <dan@cgsoftware.com>
* values.c (value_static_field): Handle static fields that have a constant value.
Abstract out operations specific to particular C++ ABI's, and
invoke them through a function table. This removes the C++ ABI
dependencies scattered throughout the code, and allows us to
cleanly add support for new C++ ABI's.

virtual_base_index_skip_primaries): Same.

(c-typeprint.o, c-valprint.o, dbxread.o, eval.o, gdbtypes.o,
jv-typeprint.o, symtab.o, linespec.o, typeprint.o, valops.o): Add
dependency on $(cp_abi_h).
* values.c (value_primitive_field): Copy VALUE_REGNO as well.
With typed registers we may have the location information in this field,
in addition to VALUE_ADDRESS (which was already being copied).

value_from_longest.
* blockframe.c (generic_push_dummy_frame): Use read_pc and
read_sp, not read_register.
* c-valprint.c (c_val_print): Use extract_typed_address instead of

remove, or check status of hardware watchpoints for entire structs
and arrays unless the user explicitly asked to watch that struct
or array.

on the value chain, even if some of them fail to insert.
